r 'u al! whom .it may concern:

lle it known that l, CARLTON R. RADCLIFFE, a. citizen of the United Sintes, residing in the city, county, and Sinto of New York, have invented certain new and usei'ul Improvements in Vdporizers, of which the following is s iull, clear, und enact description.

My invention relates to vaporizers for internal coinhustion engines and the like.

The object is to provide effective means for mixing in uniiorru proportions liquid uel with air, so as to prof" duce un explosive mixture or gas.

ln the drawings Figure l is a vertical section of the entire apparatus. Fig.l 2 is e section taken on a horizontal plane directly above the part 17a. Fig. 3 is a plan view of sfr'lout and valve o rating lever. Fig. 4 is o plsu view partly in section'o certain other details of construction. Fig. 5 isa side elevation partly broken away of the seme details. Fig. 6 a side elevation of Fig. 7 is a plan view thereof.`

l is e reservoir oi annular form for holding liquid fuel. "he central upwardly extending passage through seidv reservoir is utilized es the admission pessage for air. 2

, is a iioat located within the reservoir ndamnged tof. operate upon e. valve or closer 3 in the iuel inlet piped.'v

5 is a hiiurceted lever or yoke pivoted atand hoving e. short zum arronged to bear under the valve 3.' -The free ends of the iong yoke arms rest upon the oat'2 on diainetrically opposite sides, so that said floot (being of annular form) will not be'tilted during operation, but

,will apply its lull force in closing the valve 3. By

meaneof this lient the supply valve 3 is closed when the fuel has attained s. certain height in the reservoir 1. As. the iuel is cons uned, the ioatvdescends and valve 3 opens, admitting more. fuel, and so on. i

8 is e fuel nozzle, the dischrge end oi which projects upwardly in idle eir'edmission passage. -The upper end of thisnozzle stands et approximately the normal level of the hiel in the reservoir 1. The liquidy fuel within the reservoir fiows to the nozzle through the communicating passage Si.

l0 is vslve by which-the size of the passage leading to the nozzle 8 may be varied 'at will. 1

'l2 en :annular partitioning member' having side openings thereii'i, which. register with aniulnularcham-f bored outlet passage 13 leading to en. engine, orother .after explained.

'destiifiation for the gas. These side openingsfas shown in the drawings, ,are of less cross sectional they extend upwardly, the purpose thereiorfheingehereim end si i When thevaporizer is idle, there is preferably a slight hiv comie'ctedwith eisleeveiko mem-. @umile connected. with; i. controlling rod 16. By manually moving the controlling' 16, the gate 14 exposes more or less of the perforated poil-ion oi the partition 12, and by this means the freedom of the passage of .gas to the outlet 13 may be varied at will.

17 is afunnel-shaped member, which I will term the controller, the lower or narrow part of which is concentric with the nozzle 8, while'the upper or broader part rests upon a seat 1.14"' oi damper 14 when the vaporizer'is idle. This controller 17 is suitably connected, as by e cross bar or spider 1K7 with a. stein 18.

19 is a washer resting upon an internal shouldered l portion 20 oi sleeve 15.

21 is a spring within sleeve 15, one end of said spring hearing on the washer 20', the other end bearing against an adjustable abutment'22 also carried by the sleeve 15.

. By moving the abutment 22 up or down, the degree oi compression of the spring 2l may be varied et will.

4The stem 18 is reduced in diameter, and the shoulder formed thereby is located directly rrnder washer 19.

clearance space between said shoulder and washer, as

shown in the drawings.

23 is a cover plate for the reservoir l, and the fuel supply pipeli and valve 3 are connected therewith. So ,also is the lever yoke`5. This ycover plate, being of en nular form, may be adjusted around at any desired angle to facilitate the ready connection of the fuel supply pipe thereto. While this feature is .not of th'e essence of t e invention, it is nevertheless e. feature of convene "ience and advantage.

,Operationz When suction occurs'in the outlet 13,air will -be `drawn in through the central screened opening and will rush up through the funnel-shaped controller past the nozzle 8 5 and a certain amount of fuel will be drawn out, depending upon'the volume of sir passing said nozzle. This formsl a gas which then passes through the openings in partition 12 and into the outlet chamber 13. v A small portion oi air may bepennitted to. normally pass through the space between the tiered upper. portion of the .funnel-shaped controller 17 and seat l `Thisis possible by'reason of the slight clearance l;- tweenthe shouldered part ofthe stem 18 and the Washer, 19, which permits the inrushing uit to readily lift the controller 17. This is of advantage in the easy starting of the engine, although it is not n. eature which is of 100 of iiel to form an explosive mixture. Shouida larger 165 denland forl ges be mafie, end should e larger volume of 'airbe required, this lerger volumeof air will lift the ontlellswlf m5/from sesti14,.ailowing more airft lliow the controller rather thanthrough it.- "L I y have mixed mutated mrbuditinefmfiwqt thu/,1.10 i

effected before that time.

l i v I permit unmixed air to'flow into the mixing chamber above controller 17, that toov great a proportion of fuel to `air would `be drawn into the mixing chamber, and too rich a mixture would result. This, however,V is 'corrected by the additional air which is permitted to enter around controller-'17 and `past seat 14u. The relative amount oi` air that can enter by this coursel is determined automatically by the tension of the spring 2l, which may be set by testand experiment in each particular case. When the proper adjustment of said spring has been effected, .it Will. b e found that the relative-proportions o'f air and fuel in the gaswill be substantially uniform, Whether the demand for volume be great or small.

As before described, the stem ldmay be'moved to elevate or depress the damper .14 to close or open respectively the outlet passages in the partition 12.' By

this arrangement, the air and fuel are effectively mixed before passing to the motor,`and quick and effective combustion is assured. Bythis arrangement, the nozzle being centrally located with respect to the fuel chamber', there is no danger of flooding or overflowing the same in the event the apparatus is tilted. By having the-mixing chamber central with respect to the chambered outlet 13, it gives a relatively large space inwhich to effectively mix the air and uel before it is conveyed to its destination. Byhaving the outlets in the Wall of partition 12 extend entirely around the mixing chamber, the gas is ,delivered in all directions through. a multitude of passages, which of itself tends to guarantee the effective adniixture of vfuel andv air, should, for any reason, that admixture be `imper'fectly By having the cross sectional area of the outlet passages in thepartition l2 in creased as they descend, the slightest operation-of the v damper 14 secures a quick and effective response.

These and other advantages will be found to result from the use o1' the apparatus described. i
